Preeclampsia (PE) may affect the risk for future cardiovascular disease. Haptoglobin (Hp), an acute phase protein with functional genetic polymorphism, synthesized in the hepatocyte and in many peripheral tissues secondary of oxidative stress of PE, may modulate that risk through the antioxidant, angiogenic, and anti-inflammatory differential effects of their genotypes. We performed a prospective study in 352 women aged 35 ± 5.48 years, which 165 had previous PE, 2 to 16 years ago. We studied demographic, anthropometric, and haemodynamic biomarkers such as C-reactive protein (CRP), myeloperoxidase (MPO), and nitric oxide metabolites (total and nitrites), and others associated with liver function (AST and ALT) and lipid profile (total LDL and cholesterol HDL, non-HDL, and apolipoproteins A and B). Finally, we study the influence of Hp genetic polymorphism on all these biomarkers and as a predisposing factor for PE and its remote cardiovascular disease prognosis. Previously preeclamptic women either hypertensive or normotensive presented significant differences in those risk biomarkers (MPO, nitrites, and ALT), whose variation may be modulated by Hp 1/2 functional genetic polymorphism. The history of PE may be relevant, in association with these biomarkers to the cardiovascular risk in premenopausal women.
子痫前期(PE)可能会影响未来患心血管疾病的风险。触珠蛋白(Hp)是一种具有功能基因多态性的急性期蛋白,在肝细胞以及由于PE氧化应激继发的许多外周组织中合成,其不同基因型的抗氧化、血管生成和抗炎差异效应可能会调节这种风险。我们对352名年龄在35±5.48岁的女性进行了一项前瞻性研究,其中165名在2至16年前曾患过PE。我们研究了人口统计学、人体测量学和血流动力学生物标志物,如C反应蛋白(CRP)、髓过氧化物酶(MPO)和一氧化氮代谢产物(总量和亚硝酸盐),以及其他与肝功能(AST和ALT)和血脂谱(总低密度脂蛋白、胆固醇高密度脂蛋白、非高密度脂蛋白以及载脂蛋白A和B)相关的指标。最后,我们研究了Hp基因多态性对所有这些生物标志物的影响,以及作为PE及其远期心血管疾病预后的一个易感因素。既往患有子痫前期的女性,无论高血压还是血压正常,在这些风险生物标志物(MPO、亚硝酸盐和ALT)方面均存在显著差异,其变化可能受Hp 1/2功能基因多态性的调节。PE病史可能与这些生物标志物相关,影响绝经前女性的心血管风险。
